SD-WAN is an acronym for software-defined networking (SDN) in a wide area network (WAN). SD-WAN simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. This concept is similar to how software-defined networking implements virtualization technology to improve data center management and operation.

A key application of SD-WAN is to allow companies to build higher-performance WANs using lower-cost and commercially available Internet access, enabling businesses to partially or wholly replace more expensive private WAN connection technologies such as MPLS.

Yuvaa's SD-WAN is a resilient SD-WAN which reduces network downtime. To be resilient, the technology must feature real time detection of outages and automatic switch over (fail over) to working links. SD-WAN communication is usually secured using IPsec, a staple of WAN security. SD-WANs can improve application delivery using caching, storing recently accessed information in memory to speed future access.
